problem of mshwkorr.dll gel full scans

Hi, someone help with this problem:-running full on either Ms security esentials scan or an anti-malware program to C:\Program Files\Common Files\Microsoftshared\ink\mshwkorr.dll is scanned it little stops the analysis to which all programs gel including the Task Manager. Other anti-spyware/virus programs either do not actually analyze the file or if it is accepted.  This has happened for several weeks.  Not sure it's the scanner or the files at the root of the problem.

Hi Chris,

A box pop up came on the Windows screen saying to another disk check (which several already finished because of the forced, which had fixed some small errors) and check both boxes.

I followed the instructions and it was specifically this file in the windows winsxs folder and fix the bad clusters.  No other signs of problems I have therefore been able to run a full scan on both my usual programs anti-virus and antimalaware and they both ended with no sign of any attack.  So I'm a happy Bunny!

Thanks a lot for all your help and your time.

Thanks also to a different Chris (?) TJs) who put a list for someone else on the measures to be taken to check your hard drive, including the verification of drivers and the dust in the computer.  It can be a factor for me that the machine worked hot lately and I have pet hair!

Thans again, you are all very useful for us and our computers mistreated.

  • My Windows XP has problems with shlwapi.dll

    My Windows XP has problems with shlwapi.dll and there are plenty of sites to download, but they all want money, why don't misrosoft not has an answer for this problem. When I try to update to internet explorer 6 to explore 8 then the error always pops up saying: you have a problem with shlawpi.dll and he can not continue... Very very frustrating.

    In general, it is not a good idea to download dll files.   See, for example, http://pcsupport.about.com/od/findtheproblem/qt/dll-download.htm

    If you explain more in detail what your problem is, including providing the full text of the error without paraphrase, it is likely that someone in the appropriate Microsoft Answers forum will be able to help.

    Because it seems that your problem is related to Internet Explorer, you are more likely to receive help if you post in the forum Internet Explorer, where there are already many threads dealing with issues of shlwapi.dll on IE: http://answers.microsoft.com/en-us/Search/Search?SearchTerm=shlwapi&CurrentScope.ForumName=ie&CurrentScope.Filter=&askingquestion=false

    If you look through some of these threads, you can find the answer to your question without further delay.  If not (or if you just want to watch), do not forget to include not only the text of the error message, but also the version of Windows XP, you have (Home, Pro, Media Center) and its service pack (start > run > winver > OK).

    And, based on this thread - with what seems to be your exact problem - also include responses to the following questions (there no answer, certainly because the OP has NOT provided to the request for information):

    1. what application or anti-virus security suite is installed and is your current subscription?  What anti-spyware (other than Defender) applications?  What third-party firewall (if applicable)?

    2. do you have a free trial Norton, or a test of free McAfee [a] come preinstalled on the computer when you bought it? (No matter if you have never used or activated).

  • Query not using Full Scan Index

    Hello world

    I'm on 11.2.0.3.0 AIX 6.1.

    There is a query such as:

    Select: sys_b_0 | Count (distinct (column_name)) table;

    that goes for the analysis full table. The column was values separate only 104 with not NULL values. To save memory buffer gets, I created an index on the table with the column used in the query (i.e. whose distinct values are recovered).

    The problem is that even after the creation of indexes and force the flag index that it does not use the full scan of the index. The provided indication is correct in syntax and was the only clue in the query, so there is no question of conflicts with others.

    Can anyone suggest me what I might be missing?

    Thank you

    It seems to me that if print_branch_code is defined as nullable in the table. If this is the case, the optimizer goes for a sweep of index, even if there is no real NULL values

  • Why the optimizer ignores Index Fast full Scan when much lower cost?

    Summary (tracking details below) - to improve the performance of a query on more than one table, I created an index on a table that included all the columns referenced in the query. With the new index in place the optimizer is still choosing a full Table Scan on an Index fast full scan. However, by removing the one query tables I reach the point where the optimizer suddenly use the Index Fast Full Scan on this table. And 'Yes', it's a lot cheaper than the full Table Scan it used before. By getting a test case, I was able to get the motion down to 4 tables with the optimizer still ignoring the index and table of 3, it will use the index.

    So why the optimizer not chooses the Index Fast Full Scan, if it is obvious that it is so much cheaper than a full Table Scan? And why the deletion of a table changes how the optimizer - I don't think that there is a problem with the number of join permutations (see below). The application is so simple that I can do, while remaining true to the original SQL application, and it still shows this reversal in the choice of access path. I can run the queries one after another, and he always uses a full Table Scan for the original query and Index fast full scan for the query that is modified with a table less.

    Watching trace 10053 output for the two motions, I can see that for the original query 4 table costs alone way of ACCESS of TABLE UNIQUE section a full Table Scan. But for the modified query with a table less, the table now has a cost for an Index fast full scan also. And the end of the join cost 10053 does not end with a message about exceeding the maximum number of permutations. So why the optimizer does not cost the IFFS for the first query, when it does for the second, nearly identical query?

    This is potentially a problem to do with OUTER joins, but why? The joins between the tables do not change when the single extra table is deleted.

    It's on 10.2.0.5 on Linux (Oracle Enterprise Linux). I did not define special settings I know. I see the same behavior on 10.2.0.4 32-bit on Windows (XP).

    DETAILS
    I've reproduced the entire scenario via SQL scripts to create and populate the tables against which I can then run the queries. I've deliberately padded table so that the length of the average line of data generated is similar to that of the actual data. In this way the statistics should be similar on the number of blocks and so forth.

    I mentioned that it is a bug related to the ANSI SQL standard and transformation probably.

    As suggested/asked in my first reply:
    1. If you use a no_query_transformation then you should find that you get the use of the index (although not in the plan you would expect)
    2. If you use the traditional Oracle syntax, then you should not have the same problem.

  • HP all-in-one 4620: uninstalled 4620 printer but getting 'problem starting HPStatusBl.dll' notice at startup.

    I uninstalled the printer software HP 4620 on my HP computer running Windows 8.1. When you start the computer, I get the message "error loading c:\programfiles\hp\hpofficejet4620series\bin\hpstatusbl.dll" window message

    Hey @SteveJG,

    I would like to help you today to solve the 'problem starting HPStatusBL.dll' message that you get on your computer Windows 8.1. I understand that the uninstall your HP Officejet 4620 e-all-in-one printer has not made a difference. Just so you know, this error message is for a 'service' that Windows is trying to start it's related to the HP device. I just go and delete this file manually. Please follow the steps below.

    1. Open the Start screen by selecting the Windows button in the bottom left of your computer screen, or by clicking the Windows button in the bottom left of the keyboard, to the right of the Ctrl key.
    2. When the splash screen opens, type computer (can show that This PC)
    3. Click on the computer (or PC) to start the window
    4. When the computer window opens, click on the Drive C
    5. Click on users

    12. Select programs
    13. Finally, click Start
    14. You will see a shortcut here to monitor alerts - ink HP xxxxx. Right click on this and 'Remove' it.

    Once the file monitor ink Alters has been removed, restart your computer to verify that the problem has been resolved.

    Please reply to this message with the result of your troubleshooting. Good luck!
